Chucking my 2p in I would have thought you will be able to enjoy the occassional trip offshore as crew and, more importantly, get to use your own as often as you want in the wonderfull inshore waters.
I wouldn't compromise on launching / running costs and fishability therefore -
or to put it anotherway if I were buying you a retirement present it would be a 520/580? orkney with about a 40 hp 4 stroke motor and a bit of shelter........
up untill a couple of weeks ago when was the last trip to the rips by the warrior brigade?
